I disagree just with the "all improved, radically new, 50% more for the
same price" ad-campaign I've seen.

I don't like the fact that you said that you don't want to worry about
2.4.x because you don't think it can be fixed it as it stands. I think
that's a cop-out and dishonest. I think I've explained why.

I could fully imagine doing even multi-lists in 2.4.x. I think performance
bugs are secondary to stability bugs, but hey, if the patch is clean and
straightforward and fixes a performance bug, I would not hesitate to apply
it. It may be that going to multi-lists actually is easier just because of
some thins being more explicit. Fine.

But stop the ad-campaign. We get too many biased ads for presidents-to-be
already, no need to take that approach to technical issues. We need to fix
the VM balancing, we don't need to sell it to people with buzz-words.
